Answer:

x-intercept #= -1#, y-intercept #= -4#

Explanation:

Intercept form of linear equation is #x/a + y/b = 1#

Given #y = -4 -4x#

#4x + y = -4#

#x/-1 + y / -4 = 1# is the intercept form equation.

x-intercept #= -1#, y-intercept #= -4#

Answer:

#"x-intercept "=-1," y-intercept "=-4#

Explanation:

#"to find the intercepts, that is where the graph crosses"#
#"the x and y axes"#

#• " let x = 0, in the equation for y-intercept"#

#• " let y = 0, in the equation for x-intercept"#

#x=0rArry=-4-0rArry=-4larrcolor(red)"y-intercept"#

#y=0rArr-4-4x=0rArrx=-1larrcolor(red)"x-intercept"#
